Any particularly interesting games for a 42S/DM42/Free42 or older models?

Interesting is in the eye of the beholder, but...

There are tons of games for the HP 41 that are part of the software base in the HP 41CL.

Here is the write-up for a small 4K rom of games based on HP67 games from the PPC Journal. The manual in the link below includes game program listings and instructions.

Comments on the documentation style, contents, etc. are welcome.
